If you are about to upgrade — upgrade to Spyglass. Even if you don't need the camera overlay all you need is Spyglass app only. Since version 2.2 it has an option to turn camera off to save battery power. The Commander Compass has the same price. It is maintained in the store to support existing users and to provide free updates.
Now you can download the draft of the new, much better user guide we are working on. Help us to make it even better — please, read it and send us a message to let us know what you think. As soon as the new manual is complete we’ll translate it to all major languages.
